Syrian activists claim militants from the Islamic State of Iraq and Syria (ISIS) seized earlier this week a cache of weapons airdropped by U.S.-led coalition forces that were meant to supply Kurdish fighters battling the extremist group.

The Britain-based Syrian Observatory for Human Rights said the militants seized at least once cache, but may have seized more, the Associated Press reported.

The cache of weapons included hand grenades, ammunition and rocket-propelled grenade launchers, according to a video uploaded by a media group loyal to ISIS, the agency said.

The video appeared authentic and corresponded to The Associated Press’ reporting of the event.

The Observatory, which bases its information on a network of activists on the ground, said the caches were airdropped early Monday to Kurds in the embattled Syrian town of Kobane that lies near the Turkish border.

The militant group has been trying to seize the town for more than a month now, causing the exodus of some 200,000 people from the area into Turkey. While Kurds are battling on the ground, a U.S.-led coalition is also targeting the militants from the air.

On Tuesday, ISIS loyalists on social media posted sarcastic thank you notes to the United States, including one image that said, “Team USA.”

But the badly-aimed weapons drop was more an embarrassment than a great strategic loss. The ISIS militants already possess millions of dollars-worth of U.S. weaponry that they captured from fleeing Iraqi soldiers when the group seized swaths of Iraq in a sudden sweep in June.

Also Tuesday, Syrian government airstrikes hit a rebel-held town along the country’s southern border with Jordan, killing at least eight people on Tuesday.

Activists with the Local Coordination Committees (LCC) and the Britain-based Observatory said the number of those killed was likely to rise as there are more victims under the rubble.

The LCC said Syrian government planes dropped crude explosives-laden canisters on the town of Nasib on the Syria-Jordan border.

The air strikes are part of battles between Syrian government forces and Islamist rebel groups for control of the area.

Syrian government forces have been heavily bombing rebel areas in recent weeks, while the U.S-led coalition has been conducting air strikes against ISIS militants elsewhere in Syria.
